"frog dev" command fails due to Bun integration issue

[matthewmorek]

Describe the bug

When running the frog dev command, an error occurs related to the Bun integration with hono/bun. The error suggests that Bun is not defined, which prevents the development server from starting correctly, though this is incorrect because Bun is available in the system.

Looks like Frog is not reading Bun dependencies correctly, although the bun serve runs perfectly fine. This affects local development environment only.

Full error log:

- import { serveStatic } from 'hono/bun'
+ import { serveStatic } from 'frog/serve-static'

[matthewmorek]

If that's the case, the Frog integration docs for Bun need to be updated as they currently guide people to add hono/bun instead, causing the issue to begine with. See below:
